Q: Question: What was the first year of the show where Scion was first introduced? Passage:Scion was marketed as a youth brand and was first introduced in March 2002, at the New York Auto Show. There were just two concept vehicles, the bbX (which became the xB), and the ccX (which became the tC). The 2004 xA and xB were unveiled at the Greater Los Angeles Auto Show on January 2, 2003. They were available only in 105 Toyota dealerships in California at their initial launch on June 9, 2003. The subsequent rollout of the brand to the South, the Southeast, and the East Coast occurred in February 2004. Scion vehicles were available nationwide in June 2004, coinciding with the release of the 2005 tC. On December 16, 2006, Scion unveiled the next-generation xB, based on the t2B concept, and the new xD, successor of the xA, at an invitation-only, no-camera event in Miami. Both cars were then publicly unveiled on February 8, 2007 at the Chicago Auto Show. The xD, a 5 door-subcompact car that is sold in Japan as the second generation Toyota ist, was based on the Yaris platform with the tenth-generation Corolla's engine.
